To all whom-it may concern: 7

Be it known that I, WILFRID G. GHAUSSE, a subject of the King of Great Britain and Ireland, residing at Detroit, in the county of Wayne and State of Michigan, have in-,

vented certain new and useful Improvements in Portable Heaters, of which the following isa specification.

This invention relates to improvements in portable heaters.

The objects of this invention are:

First, to provide a simple, durable and compact portable heater especially adapted for use in heating asphalt pavements in connection with the repairing thereof.

Second, to provide a portable heater comprising a spring supported main frame mounted on wheels for transportation and carrying a heating element, which, when in operative position, is supported in a horizontal plane near the .ground, and which can be folded back upon the main frame when not in use. I

Third, to provide a portable heater having a hood carrying a battery of burners and having adjusting means for raising and lowering the hood to regulate the heat.

Further objects and objects relating to economies of manufacture and details of construction will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure constituting a preferred em bodiment of my invention is clearly illustrated in the accompanying drawings forming part of this specification in which:

Figure I is a top plan view of a heater with the hood in operative position.

Fig. II is a view in side elevation showing the hood folded back upon the ma n frame.

Fig. III is a view in end elevation show- Fig. VI is a fragmentary, detail, elevational view showing the position of the supporting links when the hood is folded back on the main frame.

F i VII is a detail, sectional View on the line 7 of Fig. II showing the construction of the walls of the hood.

In the drawings, similar reference characters refer to similar parts throughout the several views, and the sectional views ar taken looking in the'direction of the little arrowsat the ends of the sectional line s.

Considering the numbered parts of the drawing, my improved heater comprises a main frame 10 provided with the legs .9 and supported by the springs 11 mounted on the axle 12 which carries the wheels 13. A fuel tank 14 is supported from the forward part of the main frame by. means of the straps 15. The frame 10 also carries a tool box 16' and has a tongue 17 by means of which the heater may be drawn about.

To the rear ends of the side members of the main frame 10 are secured the bracket plates 18each of which carries the pivot pin 19 and is provided with the curved slot 20 concentric therewith. A swinging frame consisting of the bars 21 connected and braced by the'cross bars 2 2'is carried by the pivot pins 19 passing through the bars 21. Each bar 21 carries a threaded post extending through the corresponding slot 20 and provided'with a clamping nut 23 by which the swinging frame may be held in adjusted position.- Brackets 24 are secured to the lower ends of bars 21 and ,thefbars 25 are pivoted thereon by the pins 26. Toggle links 27 are pivoted to the bars 21 and 25 the inner ends of said links being con-- nected by pins28.

When the hood is in operative v position, as shown in Figs. I and IV, the toggle links 27 are extendedand the bars 25 extend rear- ,wardly from the main frame 10 in a horizontal plane lower than the plane of the main frame. The hood29, comprises the top wall 30, the sidewallsfil .and the end wall 32. The hood is secured to the bars 25 by bolts 33. A plurality of burners 34 are carried by the end wall 32 extending through said wall as shown in Fig. III. v

A manifold or distributing pipe 35 is carried by the forward ends of the bars 25. This pipe has a T-coupling 36 and a ut-off valve 37 for each of the burners 34 and the feed pipe 38 of each burner is detachably connected to the corresponding cut-off valve 37. By this means, each of the burners can be shut off and removed independently of the others. A pipe 39 leads from the tank 14 to the rear end of the main frame said pipe being provided with the shut-0E valve 40. The pipe 39 is Connected with the distributing pipe 35 by the flexible'connecting tube 41. 7 a

Links 42 are pivoted to the rear ends of the bars 25 and carry the apron 43 which closes the open rear end of the hood 29 and is adjustable with reference thereto so as to control the heat in some degree. Links 44 are pivoted to the side-walls 31 of the hood and carry at their rear ends the casters 45 which, when the hood is in operative position, rest on the ground and assist in supporting the hood. Brackets 46 aresecured to the side walls 81 and rods 47 are threaded in said brackets, the lower ends of said rods being secured to links 44 while'the upper ends are provided with handwheels 48 for turning the same. By this means the casters can be raised or lowered so as to vary'the height of the hood above the ground thus, in some degree, regulating the heat.

In Fig. VII, 1 have shown a sectional view through the hood showing the construction of the walls thereof. This comprises the outer metal wall 49', the layer of herringbone metal lath 50 which is placed next to the outer wall, the layer of asbestos 51 placed next to the metal lath, and the wire 'mesh 52 placed over the asbestos and held in place by the strips 53 secured by the bolts 54. The metal lath 50 forms an air chamber between the asbestos 51 and the outer wall 49 and helps to keep the outer wall cool.

Brackets 56 are attached to the side-members of the frame 10, near the forward end thereof, said brackets being provided with the slots 57 The catches 58 are fastened on the ends of the rod 59 which is journaled in the brackets 56 and provided at one end with the offset portion 60 which serves as a handle. Fins 61 are provided on the bars 25 and enter the slots 57 when the hood is folded back on the main frame, being engaged by the catches 58. Springs 62 are provided which hold the catches 58 normally in engagement with said pins.

From the description of the parts given above, the operation of this heater should be readily understood. In Fig. 11 the heater is shown ready for transportation. The tank 14 is carried by the forward end of the main frame and, when the hood is folded back, the burners 34 are located near the rear end of the main frame so that the of the burners 34.

weight of the. tank 14 balances the weight The main frame, and conser uently the hood and burners, are carried by the springs 11 so that the operative to by the catches 58 engaging the pins 61.

To release the catches 58, the rod 59 is turned by the handle 60. Having released the catches 58, theoperator lifts the hood 29 the bars 21 turning on the pivots 19. This brings the parts to the position shown in Figs. HT and V with the hood in a vertical position. The hood may be maintained in this position by. tightening the clamping nuts 23. This vertical position is the position for starting the burners as the receptacles 84 may be filled with oil to heat the burners in starting. After the burners are started the hood is lowered to operative position, as shown in Figs. T and TV, the bars 25 turning on the pivots 26. This brings the hood into a substantially horizontal plane with the lower. edge of the hood nearly touching the ground. The front end of the hood is supported by the casters 45 and, by raising and lowering these casters, the heat can be regulated somewhat. The heat can also be regulated by adjusting the apron 43.

The burners 84 are arried by the end wall 32 of the hood and are of the kerosene burning type. The fuel is carried under pressure in the tank l4 and passes through pipe 39 and the flexible connectingtube 41 to the distributing pipe 35. Each of the burners 34 is detachably connected to said distributing pipe and is provided with a cutofi' valve 37 so that each burner can be disconnected and removed independently. The position shown in Figs. I and IV is the normal operative position of the hood but the hood can be moved to either of the positions shown in Figs. 11 and III while the burners are working. With the hood in the position shown in Fig. 11 it can be used for heating tools which are placed in'the hood. With the hood in the vertical position it can still be used for heating, or the burners can be adjusted to burn with a luminous flame, the hood acting as a reflector to direct the light upon the work. i

I have shown a heater provided with a battery of five burners. The number of burners will vary depending upon the size of the hood. This heater might also be made with a single burner in place of a battery of burners.

T am aware that the particular embodiment of my invention, here shown, can be departed from onsiderably without departing from the spirit of my invention and, therefore, I do not wish to'be restricted to the same except as required by the scope of the appended claims. however, I have found that this particular structure is desirable frOm many standpoints and, hence I desire to claim the same specifically as well as broadly as indicated by the appended claims.
